Form

This specification covers a corrosion and heat-resistant steel in the form of work-strengthened bars and wire 1-1/4 inches (31.8 mm) and under in nominal diameter or least distance between parallel sides.

Application

These products have been used typically for parts, such as fasteners, requiring room-temperature minimum tensile strength of 200 ksi (1379 MPa) after precipitation heat treatment for use up to 1000 °F (538 °C) and having oxidation resistance up to 1200 °F (649 °C), but usage is not limited to such applications.
